Liverpool experienced a momentous campaign last season. Losing just four matches in all competitions, they got their hands on two trophies and could so easily have lifted two more as their bid to win an unprecedented quadruple fell short at the final hurdle.
After being pipped to the Premier League title on the last day by Manchester City, the FA Cup and Carabao Cup then lost the Champions League final 1-0 to Real Madrid.
But, as much as that loss in particular will have hurt Jurgen Klopp and his team, the Liverpool boss knows the importance of striking back. Using defeats to improve is one of his true specialities.

Around two years ago, Klopp, Peter Kraweitz and Pep Lijnders were asked how they achieve consistency after disappointing results. "You can never lose, you can only learn," said Kraweitz.
"A defeat is only a waste of time if you don't learn from it," Klopp said. "If you learn from it, it can be the most important game of the whole season."
The words of the Reds coaches are curious once assessing their summer transfer business in response to the Champions League final. It could be argued the signings they have made could stem from the high-profile loss to Madrid manager Carlo Ancelotti in Paris.
The cultured Italian has a strong managerial record against Klopp, winning five of their meetings, losing three and drawing three. In fact, of the 19 opponents Klopp has faced at least 10 times, his record against Ancelotti is his third-worst in terms of points acquired per match.
After beating Liverpool in the Champions League final, Ancelotti described Klopp's side as "easy to decipher" in his post-match comments.
The Reds, of course, have used 4-3-3 on a regular basis for many years, with Ancelotti going up against that system deployed by Klopp several times. He seems to know what to expect and his words after the final almost suggested Liverpool are somewhat predictable.
Although Klopp won't want to hear such comments, he is fond of Ancelotti and upon inspection of the club's transfer activity this summer, it is reasonable to suggest that changes are being made to ensure the same thing doesn't happen again.
Darwin Nunez was officially announced by the club last week, having arrived from Benfica for an initial fee of £64m. Unlike the typical Liverpool forward, Nunez stands around 6ft 2in and he's more in the mould of a striker than the likes of Sadio Mane and Mohamed Salah.
Signing the Uruguayan international was an unorthodox move for the Reds to make - and the same could be said about their capture of Fabio Carvalho.
The teenage star agreed to join Liverpool from Fulham this summer after thriving throughout last season having been deployed as a No.10 by Marco Silva.
Klopp doesn't tend to operate with a No.10 but, through the acquisition of the Portuguese-born attacker, the option to fluidly change formations has opened up, especially considering Carvalho could also perform as a wide forward and as a No.8 in midfield.
Liverpool have always demonstrated an interest in players who are tactically flexible but next season Klopp will be presented with the tools to realistically dovetail between at least two primary formations in 4-3-3 and 4-2-3-1.
Rather than using the latter shape around just 10% of the time, perhaps Klopp will switch things up with greater regularity to make sure his team aren't easy to analyse moving forward.
Ultimately, Ancelotti might have inadvertently shaped the Reds' window this summer.
